Yes, but since the associated peripheral is disabled, the users are free to configure other functions/peripherals, right? I mean something like this in pseudo-DT:

/soc/pio: pinctrl@01c20800/uart1_pins:
allwinner,pins = "PG6, PG7";
/soc/pio: pinctrl@01c20800/foo0_pins:
allwinner,pins = "PG6, PG7";
..
/soc/uart1: serial@serial@01c28400:
pinctrl-0 = <&uart1_pins>;
status = "disabled";
/soc/bar:
pinctrl-0 = <&uart1_pins>;
status = "disabled";

Assuming Linux/DT allows this, this would force nothing, only offer choice and ease of use.

Best,
